CVE-2024-40333 is a Cross-Site Request Forgery (CSRF) vulnerability identified in idccms version 1.35, a content management system. The vulnerability resides in the /admin/softBak_deal.php script, specifically when handling requests with the parameters mudi=del and dataID=2, which appear to trigger deletion operations. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to perform unintended actions by submitting crafted HTTP requests without their knowledge. This particular vulnerability does not require any privileges or authentication bypass since it targets authenticated users, but it does require user interaction (such as clicking a malicious link or visiting a crafted webpage). The CVSS 3.1 base score of 8.8 reflects a high severity due to the network attack vector, low attack complexity, no privileges required, but requiring user interaction, and the impact being high on confidentiality, integrity, and availability. The CWE-79 tag suggests that the vulnerability may also involve cross-site scripting elements or improper input validation, but the primary issue is CSRF. No patches or exploit code are currently publicly available, and no known exploits in the wild have been reported. However, the vulnerability poses a significant risk to organizations using idccms 1.35, especially those exposing administrative interfaces over the internet. Attackers could leverage this flaw to delete critical data or perform other administrative actions, potentially leading to data loss, service disruption, or full system compromise.

The impact of CVE-2024-40333 is substantial for organizations using idccms version 1.35, particularly those with administrative interfaces accessible externally. Successful exploitation can lead to unauthorized deletion of data or configuration changes, resulting in loss of data integrity and availability. Confidentiality may also be compromised if attackers manipulate administrative functions to extract sensitive information. The vulnerability could disrupt business operations, damage reputation, and incur financial losses due to downtime or recovery efforts. Since the attack requires an authenticated administrator to be tricked into executing the malicious request, organizations with poor user security awareness or weak session management are at higher risk. Additionally, if the CMS is used in critical infrastructure or government websites, the consequences could extend to national security or public trust. The lack of known exploits currently reduces immediate risk but does not diminish the urgency of mitigation given the high CVSS score and ease of exploitation once a user is targeted.

To mitigate CVE-2024-40333, organizations should first check for any official patches or updates from the idccms vendor and apply them promptly once available. In the absence of patches, implement anti-CSRF tokens in all state-changing requests, especially those involving administrative actions like deletion. Restrict access to the /admin/softBak_deal.php endpoint by IP whitelisting or VPN-only access to reduce exposure. Enforce strict session management policies, including short session timeouts and re-authentication for sensitive actions. Educate administrators about the risks of CSRF and the importance of not clicking on suspicious links or visiting untrusted websites while logged into the CMS. Employ web application firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting the vulnerable endpoint. Regularly monitor logs for unusual administrative requests or patterns indicating potential exploitation attempts. Finally, consider isolating the CMS administrative interface from the public internet where feasible to minimize attack surface.
